MAMMALIA. 



Keria Mountains, which form the barrier between the valley of 

 Tarim and the plateau of north Tibet. 



Arctomys robustus of Milne Edwards (Rech. Mamm., p. 309) 

 was given by Blanford in his paper on Himalayan Marmots as a 

 synonym of A. himalayanus; Buchner in his accounts of Prze- 

 walski's Mammals holds a contrary Opinion and distinguishes A. 

 robustus by its larger size, its darker back and sides, and the 

 patch of rusty brown at the sides of the snout and round the ears ; 

 none of these characters are very decisive ones, but for the pre- 

 sent A. robustus is left separate.

Blanford's name has been adopted in preference to A. hema- 

 chalanus, which is synonymous with A. himalayanus and cannot 

 therefore stand. 



It is a curious fact that no truly feral example of this species 

 has yet been obtained ; all the specimens mentioned below were 

 caged.
